The complaint charges Par Pharma and its Board and TPG with violations of the 1934 Act. Par Pharma is a U.S.-based specialty pharmaceutical company that develops, manufactures and markets high-barrier-to-entry generic drugs and niche, innovative proprietary pharmaceuticals.

The complaint alleges that defendants failed to disclose material information in a proxy statement filed with the SEC and publicly disseminated in connection with the proposed sale of Par Pharma to TPG. According to the complaint, the proxy statement was materially false and misleading because it made numerous material omissions about the process leading up to the agreement between Par Pharma and TPG and the work performed by Par Pharma’s financial advisor, J.P. Morgan Securities LLC, which was retained by Par Pharma to evaluate the fairness of TPG’s offer.

Plaintiff seeks injunctive and equitable relief on behalf of all public shareholders of Par Pharma common stock as of August 2, 2012. Plaintiff is represented by Robbins Geller, which has expertise in prosecuting investor class actions and extensive experience in actions involving financial fraud.
